Like the swords to plowshares metaphor, the idea of turning oil-centric objects of design into post-pollution paradises is nothing new, but rarely fleshed out quite so well as in this proposal.

This idea by PinkCloud.DK involves turning old spherical oil silos into a new sustainable multifamily residential buildings Рsince they are already portable and well-sealed, the conversion is mostly additive.

With 50,000 of these sorts of structures in existence, it reminds one a bit of shipping containers: there is sufficient supply that you could imagine a refab solution being designed once and applied many times over, saving time and money through efficient repetition and deployment.

The spheres are also naturally optimized for things like adding solar panels and streamlined to channel or deflect winds as desired for natural ventilation purposes.
